Feature Request: Native Support for Antigravity CLI in Zed Agents (Replacing Deprecated Gemini CLI)

[Elitenotavailable]

Body

Google has officially deprecated the Gemini CLI for individual users and transitioned to the new Antigravity CLI (agy). As a result, the existing Gemini integration in Zed's Agent panel is no longer functional.

Proposed Feature:
Please integrate native support for the Antigravity CLI into Zed's Agents tab.

Context & Motivation:
Currently, the agy binary does not natively support the Agent Client Protocol (--acp flag). This prevents developers from configuring it as a custom agent in settings.json. To use Antigravity within the Agents UI, users are currently forced to write intermediary Node.js wrapper scripts to handle the JSON-RPC translation, or they must abandon the GUI entirely to use the integrated terminal. Native support or a built-in adapter would restore a seamless AI experience for developer
